I cannot seem to get this working correctly. I am trying to get a Cisco 3850 to talking to a HP 5920 over LACP. When I go to ping between the two devices I get nothing.
Cisco Configuration
interface Port-channel4
switchport trunk allowed vlan 2,51,400
switchport mode trunk
switchport nonegotiate
no port-channel standalone-disable
spanning-tree bpdufilter enable
!
interface TenGigabitEthernet1/0/46
switchport trunk allowed vlan 2,51,400
switchport mode trunk
switchport nonegotiate
no cdp enable
channel-protocol lacp
channel-group 4 mode active
spanning-tree bpdufilter enable
lacp rate fast
!
interface TenGigabitEthernet1/0/48
switchport trunk allowed vlan 2,51,400
switchport mode trunk
switchport nonegotiate

spanning-tree bpdufilter enable

HP Configuration
interface Bridge-Aggregation2
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 2 51 400
link-aggregation mode dynamic
interface Ten-GigabitEthernet1/0/23
port link-mode bridge

Any help would be great.

Hello,
I am not sure if the Cisco side needs 'switchport trunk encapsulation dot1q', can you give that a try ? Also, which VLAN do you have marked as tagged on the HP side ?

I was trying to keep the Cisco unchanged, but I can attempt to make that change.
As far as tagging on the HP device I think you are thinking of their other version of the OS, this one works closer to Cisco trunk method from what I have read.If I go to the vlan there is no tag command.

Also believe the switchport trunk encapsulation dot1q command has been deprecated out of the version of the Cisco software I am running. So that is not going to provide any change.

Hi,
Not familiar with HP but can you provide the info for what IP and in what vlan you are trying to ping?
Is HP layer-2 only and the gateway for all vlans on the 3850?

I am trying to just ping IP address on the same vlan right now.
So if I look at vlan 400 on both devices they look like this.
HP
interface Vlan-interface400
ip address XX.XX.XX.1 255.255.255.0ping
Cisco
interface Vlan400
ip address XX.XX.XX.10 255.255.255.0
ip directed-broadcast
end
Basically try pinging either device from the same vlan and it doesn't work.

Hello,
I am not sure how the HP 5920 handles the native VLAN, but try and remove all 'allowed vlan' commands from both the Cisco and the HP side.
Also, on a port channel between Cisco switches, it is recommended to have matching channel numbers. So try and change your interface Bridge-Aggregation2 to interface Bridge-Aggregation4...

Thanks Buddy
its Really Helpful to understand what to do with hp
